4. The apparatus according to claim 3 , wherein the control unit makes a proportion of blur correction that the other correction device is caused to perform smaller than a proportion of a blur correction that the one correction device is caused to perform.
5. The apparatus according to claim 1 , wherein the periodic operation is an operation in which an image formed by the lens is caused to move in a circle on a capturing plane of the capturing apparatus.
6. The apparatus according to claim 1 , wherein the control unit causes the correction device whose power consumption in a case of being caused to perform the periodic operation is lower, out of the first correction device and the second correction device, to perform the periodic operation.
7. The apparatus according to claim 1 , wherein the control unit causes the correction device whose drive current limit value is higher, out of the first correction device and the second correction device, to perform the periodic operation.
8. The apparatus according to claim 1 , wherein the control unit causes the first correction device to perform the periodic operation in a case where a focal length of the lens is less than a predetermined value, and causes the second correction device to perform the periodic operation in a case where the focal length is greater than or equal to the predetermined value.
9. The apparatus according to claim 1 , wherein the control unit causes the correction device whose position accuracy during minute-driving is higher, out of the first correction device and the second correction device, to perform the periodic operation.
10. The apparatus according to claim 1 , wherein the control unit causes the correction device whose magnetic field noise generation in a case of being caused to perform the periodic operation is lower, out of the first correction device and the second correction device, to perform the periodic operation.
11. The apparatus according to claim 10 , wherein the control unit, if an ISO sensitivity set in the capturing apparatus is greater than or equal to a predetermined value, causes the correction device whose magnetic field noise generation in a case of being caused to perform the periodic operation is lower, out of the first correction device and the second correction device, to perform the periodic operation.
12. The apparatus according to claim 1 , wherein the control unit, in a case of not performing the blur correction operation, causes the correction device whose power consumption in the case of not performing the blur correction operation is larger, out of the first correction device and the second correction device, to perform the periodic operation.
13. The apparatus according to claim 1 , wherein the control unit changes a drive frequency of the periodic operation in accordance with an exposure period of the capturing apparatus.
14. The apparatus according to claim 1 , wherein the control unit,
in a case where an exposure period of the apparatus is larger than a predetermined value,
further causes the other correction device to perform the blur correction operation in addition to the periodic operation, and
in a case where an exposure period is less than or equal to the predetermined value,
causes the other correction device to perform the blur correction operation in addition to the periodic operation.
15. A method comprising:
obtaining information related to a shake detected by a sensor, and
causing one correction device, out of a first correction device that is positioned in a lens and that can correct a blur based on the information related to the shake and a second blur correction device that is positioned in a capturing apparatus and that can correct image blur based on the information related to the shake, to perform a blur correction operation, and causing the other correction device, out of the first correction device and the second correction device, to perform a periodic operation.
16. The method according to claim 15 , wherein the periodic operation is an operation in which an image formed by the lens is caused to move in a circle on a capturing plane of the capturing apparatus.
17. The method according to claim 15 , further comprising changing a drive frequency of the periodic operation in accordance with an exposure period of the capturing apparatus.
18. A non-transitory computer-readable storage medium storing a program for causing a computer to function as each of units of an apparatus, the apparatus comprising:
an obtaining unit configured to obtain information related to a shake detected by a sensor, and
a control unit configured to cause one correction device, out of a first correction device that is positioned in a lens and that can correct a blur based on the information related to the shake and a second correction device that is positioned in a capturing apparatus and that can correct image blur based on the information related to the shake, to perform a blur correction operation, and configured to cause the other correction device, out of the first correction device and the second correction device, to perform a periodic operation.
